Steam jet processing device for garments

When processing many types of garments, it is often only necessary to one the garment Moisturizing agents (steaming agents), such as exposing them to steam, to soften the threads of the material and then the garment to be dried by means of a heated, dry air jet. This procedure is available with both so-called Tunnel (continuous) processing devices as well as with Insert container devices realized economically been.

A conveyor device carries the continuous processing device an item of clothing usually hanging on a clothes hanger or the like through the on both sides open processing device with a humidification chamber at the inlet end at atmospheric pressure and at the opposite end Auslaßend- a drying chamber with atmospheric pressure is provided. The advantages of this type of processing device lie in the fact that successive pieces of clothing are preferably aligned parallel to each other in a Keihe are required, with the humectant, preferably Steam, can be directed directly against the garment for thorough penetration and moistening

of the garment. Then the garments can turn in a row through relatively narrow Drying chamber tunnel walls are passed in which drying air is passed over the garment at a relatively high speed can circulate to blow it through and smooth out the wrinkles.

Dei the insert container device, a housing forms a closed space. They are means of holding one Garment within the enclosed space and to fill the entire enclosed space with one Atmosphere of a humidifying (vaporising) agent, preferably steam, provided to moisten the garment. Then the closed space is ventilated and a drying agent, preferably heated air, over the Garment headed. The combination of the steam atmosphere combined with the movement of air over the garment with an optionally mechanical shaking of the Garments by means of an auxiliary shaker, results adequate processing of most garments. The housing can preferably be dimensioned so large that more than one garment can be processed during a common processing cycle. ·

The continuous processing device has an advantage over the insert container device, namely an effective steam humidification; namely, the steam can immediately directed against the garments as they line up through the humidification chamber of the tunnel processor be guided. On the other hand, in the case of the insert container device, the clothes usually hang Side by side, so that they only serve

but not exposed to dampening agents an immediate outflow effect. However, the Einsat Z container device has another advantage over the tunnel machining device, which is that this requires significantly less boiler output, since the steam lasts longer in the closure of the insert container device lingers than in a tunnel machining device. As a result, the cost and the insert container device are lower is more suitable for smaller facilities such as local cleaning centers than for industrial machining plants.

It turns out, however, that the tunnel machining device has better machining characteristics than the insert container device, possibly because of the direct alignment of the humectant against the garments and because of the high speed of air blast drying, in particular not by sole Supplying additional steam and / or air voluraina can be duplicated in an insert container device.

The invention accordingly relates to a steam jet B '= arbe it ungsvorrichtung for processing a plurality of items of clothing, each arranged on a holder, during a single one Machining cycle, with a housing that forms a closed space with an access opening, with a door for closing the access opening, with a first conveyor device arranged within the closed space, comprises the means for holding brackets and garments thereon, the loading the brackets of the first conveyor with items of clothing, or their unloading takes place through the access opening, with a j3edienungsvorrichtung for the first conveyor

The illustrated machining device IO has a housing with opposing side walls 13, front and rear walls 14 and 15, and a floor 16 and a ceiling on. These parts form an enclosed space 20 which, with the exception of an access opening 22 on the front wall 14 in the generally closed. A closing door 24 is on vertically arranged pivot pins 26, the rotation of the Doors 24 around their central axis in the area of the access opening

2098W / 008 7

22 allow attached. When the door 24 is closed, that is, when it is aligned with the front wall 14, the closed space 20 is not necessarily closed airtight or vapor-tight; but it can only be a minor one Steam or air loss occur in the enclosed space 20.

A conveyor 30 is attached near the ceiling 17 of the housing 12, which is completely enclosed in the Space 20 is located and is generally designed as a loop. The conveyor device 30 can be known per se Construction be formed. In the exemplary embodiment, it is designed so that it has Viende gears 32 to a conventional link chain 33 is guided. A two-part tube 34 can encompass the link chain 33 at a distance, to provide basic support at locations on link chain 33 remote from sprockets 32. The tubes 34 are fastened to the housing 12 by means of brackets 35. On individual links arranged at a distance from one another the chain 33 are fastened from the two-part tube 34 depending brackets or brackets 36, each one flat have vertical surface and a hook projection 37, which are inclined upwards with respect to the surface which lies outside the loop-shaped conveyor 30. At each of the hook projections 37 hangs a clothes hanger. Along the loop 30 there are six equidistant from one another or eight brackets 36 are provided which hold the garments arranged next to one another parallel to the guidance of the conveyor device Wear 30 in such a way that an edge distance between the individual items of clothing is maintained. A guide rail 43 is attached at a small external distance from the adjacent brackets 36 below the hook projections 37,

209847/0087

around the hangers with their flax against the brackets 36 and parallel to the movement of the conveyor.

The conveyor device 30 has guides 38 and 39 and a partition wall 40 extends from the floor 16 to the ceiling 17 between the guides 38, 39. A pair of steam pipes 42 are on opposite sides of the guide 38 of the conveyor 30 and extends as it were from the floor 16 to the ceiling 17. The steam pipes 42 let the steam on the guide 38 of the conveyor 30 away from the opening 22 and in approximately the same direction as the direction of movement of the conveyor 30. This reduces the loss of steam in the opening 22 to a minimum. A wall 44 lies opposite the partition wall 40 along part of the guide 39 of the conveyor device 30. the Wall 44 and partition 40 form a drying tunnel 46 filled with vigorously moving air. The distance between the partition wall 40 and wall 44 is preferably 4 "to 6" so that one conveyed by the conveyor 30 and a garment aligned parallel to this with only a small distance between these walls to be led. A fan 48 is attached to the rear wall of the housing 12. This has an inlet opening 49, sucked in by the ambient air from the outside and then within one of the walls 15 and 44, as well as in between lying walls 53 (see Figure 2) formed passage or channel 52 is drained. An extractor hood 55 Above the ceiling 17 rotates the air flow in the duct 52 by 180 degrees, around this from a ceiling opening 56 downwards to lead into the drying tunnel 46. A gear motor 58 is attached to the ceiling 17 and connected to a gear shaft 59, to set the attached gear 32 in rotation and to drive the conveyor 3ü; a little

iO9847 / OOR7

The second motor (not shown) is used to drive the fan 48.

During the usual machining cycle of those described above Processing device are the brackets 36 of the conveyor 30 with a variety of items of clothing loaded or draped and guided through the enclosed space 20 by means of the conveyor device 30. While the humidification or evaporation phase of the processing cycle, steam is vented from the steam outlet pipes 42, which against the individual items of clothing is directed when they are guided past the tubes 42 one after the other. In addition a vapor-like atmosphere is obtained in the entire closed space 20, which in the further course of the clothing items thoroughly moistened. The duration of the humidification phase and the speed of the conveyor 30 are preferred sized so that each garment is passed between the steam outlet tubes 42 at least once. This Operation can result in thorough moistening of the garments Repeat twice, three times or more. After completion of the moistening phase of a machining cycle the fan 48 is put into operation, creating a plurality of exhaust openings 60 (Fig. 1 and 2a) in the ceiling 17 of the processing device are opened, the air slide valve 61, which is usually exposed to gravity, is closed are. A heat exchanger 62 (Fig. 2) is arranged in the air duct 52 so that the air is heated before it enters the closed space 20 is admitted in order to ventilate the atmosphere in the space 20 and those located therein Drying clothes. During the drying phase of the The air will steam up at high speed left out in the air flap or drying tunnel 46 at the bottom,

209847/0087

where it strokes directly over the items of clothing in it, causing them to be violently blown through and thus the wrinkles are driven out. The duration of the drying phase of the processing cycle is again long enough to in order that each garment is passed through the drying tunnel 46 at least once; possibly more often, so that the garment is immediately exposed to the high air velocity is exposed to smooth the wrinkles by vigorous shaking or blowing. The entire completed Room 20 thus also serves as a drying chamber, since the air circulates in it before it can be. from the vents 60 escapes.

Special means for automatic loading of the conveyor 30 with items of clothing or their removal are not described in detail. The door 24 is how mentioned, at least 180 degrees around the central pin 26 rotatable. It has opposite sides 66 and 67, which are interchangeable so that they are on the one hand in the closed space 20 and on the other hand outside of this lie. Similar sets of feed and take-up rods 68 and 69 are attached to each side of the door 24. To simplify their description, reference is made in the following to one of these sets.

The feed rod 68 consists of a shaft or rod 70 which extends from the adjacent upper edge of the door 24, the aligned under the upper pivot 26, is inclined downward. The shaft 70 ends in a terminating piece 71, which is directed inwards and is arranged at a small distance above the hook projections 37 of the conveyor device 30 (FIG. 3), The shaft 70 has a plurality of pins 74 and 76.

209847/0087

The pins 74 are all aligned and in uniform Distance distributed along the shaft 70. Likewise, the pins 76 are all aligned with one another and in uniform Distance distributed along the shaft 70. Pins 74 and 76 are offset from one another by approximately 90 degrees. Of the Shaft 70 is fastened in a holder 77 which can be rotated by approximately 90 degrees. This allows the pins 74, which are normally at the top of the shaft 70 are moved to one side and the pins 76, which are normally located on the opposite side of the shaft 70, are moved to the upper end of the shaft 70 (Figure 4). A stop 78, which rests on the holder 77 and limits the rotation of the shaft 70, is provided on the shaft 70. Between the stop 78 and the holder 77 there is a tension spring 80, which the shaft 70 in its normal position, as above described, with the pins 74 at the upper end of the shaft 70 are located. On the ceiling 17 of the housing 12, a pressure cylinder 82 is attached, the plunger 84 of which protrudes through an opening 85 in the ceiling 17 and at the stop 78, which is attached to the shaft 70, rests. When the pressure cylinder 82 is actuated, the shaft 70 rotates around on the lülle J 90 degrees so that the pins 74 are now on the side and the Pins 76 are located on the upper end of the shaft 70.

Typically, an operator can hang the hook of a conventional clothes hanger on the shaft 70. The shaft 70 would normally slide the hanger down under the influence of gravity, if not the hanger would be held up by the vertically arranged pins 74. As a rule, there are just as many pins 74 on the shaft 70 as brackets 36 are present on the conveyor 30, so

209847/0087

that a clothes hanger can be hung on each pin 74 on the shaft 70. By simply turning the door 24 around Degree the loaded shaft 70 is guided into the interior of the enclosed space 20 so that it is to the conveyor 30 assumes a position that enables the continuous transfer of each clothes hanger to the adjacent holders 36 of the dereinrichtung 30 allows. To achieve this, the Pressure cylinder 82 actuated so that it rotates the pins 74 in that side position in which all clothes hangers are released with the lowest release pin allowing the corresponding hanger with the garment to put it on the corresponding hook projection 37 of the conveyor 30 falls (Fig. 3). When the shaft 70 is oriented so are all of the pins 76 at the top thereof, so that each of the remaining hangers from the respective Pin 74 slides down until it is retained by the next vertical pin 76. When the printing cylinder 82 is relaxed, and the tension spring 80 rotates the shaft 70 back into its starting position, so each clothes hanger again released (this time by the pins 76) to slide down the shaft 70 until it passes through the next lower, now vertical pin 74 is retained. In order to achieve a uniform and quick handover, the conveyor device 30 moves continuously at its set speed, with the shaft 70 so oriented is that, with a more precise setting, the bottom coat hanger is transferred to the holder 36 that is passed by. One switch 87 can be controlled by a cam 88 which is set in rotation by the gear shaft 59 (FIG. 1), whereby the pressure cylinder 82 is automatically actuated. The switch 87 is connected to a suitable (not shown) Circuit connected so that each originally through one

209847/0087

Pin 74 restrained clothes hangers for one holder each 36 is released on the conveyor 30. The circuit is preferably designed so that it after release all of the clothes hangers from the transfer mechanism 68 cease to function.

It is noteworthy that two feed and release mechanisms 68 are provided on opposite sides of the door 24 so that one mechanism 68 is located within the enclosed space 20, while the other mechanism 68 is arranged outside of this space. Thus, an operator can read the garments to be processed apply to the free mechanism for the following machining cycle.

As already mentioned, is located below each feed mechanism 68 a receiving mechanism 69. This is very simple. It consists of a rail 90, which is rotatable at its lower end about a carrier 92, about the rail 90 between an approximately vertical position (Position 90 U in Figure 3) and an upwardly inclined, lowest position (position 90 D in Fig. 3) to move. In this In the lowest position, the free end 93 of the rail 90 is directed outwards with respect to the position of the conveyor device 30, so that any disruptive influence on the hangers and the items of clothing carried by the conveyor 30 is avoided. The rail 90 is not stable in the vertical position 90 U. Instead, it tends to be in the deepest position Able to fall 90 D. However, it can also be easily stopped in any intermediate position (Fig, 3), for example in the direction of the top item of clothing on the feed mechanism 68.

209847/0087

In the housing 12 of the conveyor 30 is a push-off or Reloading mechanism 95 is provided. The mechanism 95 consists of a rail 96 carried by a shaft 98, which in turn is rotatable in a socket 99. In this holding position, the rail 96 is usually arranged horizontally and is in line with the stem or neck portions of the clothes hangers when they are removed from the brackets 36 the conveyor 30 are carried. The rail 96 is usually supported by a spring 100 which is inserted between the housing 12 and a journal bearing 101 is attached, which holds the shaft 98 in a retracted position (Figure 3), wherein no interference with those carried by the conveyor 30 Hangers are available so that the hangers can move freely. The rail 96 can, however be disengaged by means of a pressure cylinder 102 which is fastened between the journal bearing 101 and the housing 12, to cross the plane of the conveyor 30. In this case, the rail 96 moves vertically on the holder 36 over; but it engages the stem of a garment hanger on the conveyor 30. Of the The clothes hanger is thus after the engagement of the rail 96 crossing the movement of the conveyor device 30 on the hook projection 37 of the holder 36 is moved upwards * until it falls from the hook projection 37 and onto one of the Rail 96 carried pin 104 falls. The pin 104 is inclined slightly downward, so that its free end is aligned vertically over the receiving rail 90 in its lowest position and extends beyond this, so that the hanger falls from the pin 104 onto the rail 90 and slides down the rail 90, until it is stopped by the door 24 or another item of clothing already on the rail 90. It

a discharge circuit (not shown) can be provided and, if desired, can also be designed completely automatically, which at the end of the drying phase of the processing cycle actuates the pressure cylinder 102 and the unloading machine 95 holds transversely to the direction of movement of the conveyor device 30 until all clothes hangers are transferred from the conveyor device 30 have been. This could be perceived by a limit switch in the discharge circuit (not shown), which causes that this circuit is opened after one complete revolution of the conveyor 30, the limit switch could be operated by means of a cam disc (not shown) with a suitable speed reduction gear (not shown) driven by the gear shaft 59 is connected.

In the same way, a receiving rail 90 is provided on both sides of the door 24, so that it can be in the housing 12 can receive and hold machined garments without the position of the door 24 having to be changed. The door 24 can then be rotated 180 degrees, with the operator removing the finished garments from remove the outside of the take-up mechanism 69 (Fig> ') and items of clothing still to be worked on on the top:., in « orderly feed mechanism 68 can be attached while at the same time a subsequent processing cycle for those who Garments that have not yet been processed can be started previously on the feed mechanism that is now on the inside 68 have been hanged.

There can also be means for operating the door 24 for daren Rotation by 180 degrees can be provided, for example a pressure cylinder 110 which is connected to a rack 112,

209847/0087

while the rack 112 is guided in a slide rail 113, and with a gear 114 on the pivot 26 of the door 24 is attached, engages and drives this. By suitable attachment of, for example, the rack 112 engaged stops (not shown) is when the pressure cylinder 110 is actuated in the an end position, the rack 112 is moved and accordingly the door 24 is brought into the first closed position, while when the pressure cylinder 110 is actuated in its other end position, the door 24 is exactly 180 degrees from the first closed position is rotated into the opposite second closed position.

A control device can also be provided which is controlled by a manually triggered start button is actuated to rotate the door 24 and the conveyor 30 in operation to put. Then, when the door 24 has assumed its new closed position, for example by using the Rack 112 engaged limit switches can be scanned, the control device can begin with it Unload feed mechanism 68 and start the humidification cycle. The humidification cycle including one subsequent appropriate steaming and drying phases can be controlled by suitable adjustable timers. At the end of the processing cycle, the control can automatically actuate the pressure cylinder 102 for the unloading mechanism in order to return the garments from the conveyor 30 to the carrier 90 of the pick-up mechanism 69 at the door 24 and then around the door 24 another iial to automatically set in rotation and to repeat the above for its second subsequent humidification cycle.

recover. At the end of the processing cycle, when all of the garments are collected on the inner receiving mechanism 69, only the fan 48 would be switched off, but the door 24 not rotated and no new machining cycle started, unless by the operator. That means, that an operator can load a feed mechanism 68, start the first machining cycle and in the next few moments the other side of the door 24 can unload and reload. Then the Operator leave the machine without supervision during a first and a second machining cycle is. Only then does the operator have to remove all items of clothing deposited at the door Return the machine.
